Operation Tagged Values

Both operations and the parameters assigned to operations can have Tagged Values associated with them. Tagged Values offer a convenient extension mechanism for UML objects, so you can define any tags you need and then assign values to them using this form.

Tagged Values are written to the XMI output, and can be input to other third party tools for code generation or other activities.
